摘要
提出了一种白天信标光图像跟踪算法。分析了太阳光反射进相机视场的噪声以及探测器噪声在空域和频域的特点,使用两个频域滤波器检测候选区域。研究结果表明,所提算法具有较高的精度、较快的速度以及较高的可靠性,可用于白天环境下星地信标光的跟踪探测。
Abstract
A beacon image tracking algorithm during daytime is proposed. The camera view field noise reflected by sunlight and detector noise in the spatial and frequency domains are analyzed. Two frequency domain filters are used to detect candidate regions. The results show that the algorithm has high precision, high speed, and high reliability, and can be applied to the daytime satellite-to-ground beacon tracking.
